What encompasses a geospatial layer?

The correct choice encompasses a comprehensive view of what a geospatial layer actually includes. In the context of geospatial intelligence, a geospatial layer refers to a representation of geographic information that can involve various types of data. This includes not only boundaries and infrastructure, which may refer to political borders, roads, bridges, and buildings, but also elevation data that helps illustrate how land forms interact with one another.

By integrating these diverse components, geospatial layers enable a more complete understanding of the spatial relationships and characteristics of different locations. This holistic approach is critical in various applications such as urban planning, environmental monitoring, disaster response, and military operations, where understanding the interplay between physical features and man-made structures is essential for informed decision-making.

While the other options highlight certain aspects of geospatial data, they fall short by being overly narrow or focused solely on a single type of data. Therefore, the inclusion of a variety of geospatial information makes the correct choice the most accurate representation of what constitutes a geospatial layer.
